I understand the daily and weekly sefiros combinations that are mentioned in the Ribbono Shel Olam prayer and relate to the process of refinement on the way to Shavuos. To a large extent these are relatable concepts.
But I also notice that in some siddurim they include the corresponding word of Lamnatzeach, the letter that comes from the middle pasuk, and the word in Ana B'choach that goes with the day count.
What is someone supposed to do with that information, for example that today's count goes with the letter yud and the words ארץ and גאה? Is there some advantage to knowing or paying attention to that, beyond the value of just counting the days?
